His experience also involves product design evaluation, strength of materials analysis, and failure mechanics. He has performed evaluations in the areas of pressure vessels, machine design, and thermal and fluid systems. Mr. Danaher has evaluated and analyzed heavy equipment such as skid steer loaders, motor graders, oil field equipment, off road/on road forklifts, and front-end loaders. Mr. Danaher has also investigated commercial production processes throughout the country. These evaluations included safety systems, design and operation, as well as maintenance related issues. Mr. Danaher has also worked with government agencies including OSHA to determine system failures and operator interaction on heavy equipment. ACCIDENT RECONSTRUCTION: Mr. Danaher has extensive experience performing vehicle accident investigations throughout the United States. His hands-on investigative experience includes inspections of passenger cars, motorcycles, trucks, tractor trailers, commercial vehicles and bicycles. He is experienced in analysis of vehicle speeds, crush energy, braking systems, motorcycle braking and performance, driver reaction, time-space analysis, and dynamics. Mr. Danaher has also been trained and certified on downloading and interpreting ACM and ECM ( black box ) data from passenger and commercial vehicles. He has investigated and analyzed hundreds vehicular accidents and applies his knowledge of vehicle dynamics, simulation, crush energy, momentum, and driver response to accident reconstruction. Frequent aspects of these investigations involve analysis of brakes, tires, seat belts, airbags, and other vehicle systems. Mr. Danaher also has working experience with engine, drivetrain, and suspension failure analysis. In addition, Mr. Danaher has evaluated accidents involving recreational activities and equipment. Mr. Danaher has also authored publications related to forensic engineering for the Society of Automotive Engineers (SAE) and the National Academy of Forensic Engineers (NAFE). Mr. Danaher has also presented numerous seminars regarding vehicle accident investigations and reconstruction, product design and failure analysis, seat belts and airbags, and occupant kinematics. Mr. Danaher and his accident reconstruction expertise have been featured several times on local and national television including NBC, MSNBC, and CBS. EXPERT TESTIMONY: As a result of his investigations and experience, Mr. Danaher has been qualified as an expert witness in cases nationwide and has provided expert testimony in both State and Federal Courts. PROFESSIONAL AFFILIATIONS: National Academy of Forensic Engineers, Fellow (NAFE), National Society of Professional Engineers (NSPE), Accreditation Commission for Traffic Accident Reconstruction Full Accreditation (ACTAR), Society of Automotive Engineers (SAE), National Association of Professional Accident Reconstruction Specialists (NAPARS), American Society of Mechanical Engineers (ASME) - American Society of Materials (ASM), American Society of Agricultural and Biological Engineers (ASABE). Mr. Danaher participated as a member of several SAE Standards Committees, including Reconstruction Information Resources, Investigation Techniques, Vehicle-Road Friction, and Pedestrian Accidents. Commercial Vehicle Safety Alliance (CVSA), Vehicle Committee Member. OSHA GI training.
